[−][src]Function core_arch::aarch64::__wfi
pub unsafe fn __wfi()
🔬 This is a nightly-only experimental API. (
stdsimd
)This is supported on AArch64 only.
Generates a WFI (wait for interrupt) hint instruction, or nothing.
The WFI instruction allows (but does not require) the processor to enter a low-power state until one of a number of asynchronous events occurs.
